A basic understanding can lead to better field results. At the heart of this science is coefficient of friction (COF), the measurement of which is sometimes called \u201ctribiology.\u201d There are many ways to calculate COF, however it is highly dependent on use conditions. While COF is a constant in tension equations, it is used as a dynamic factor that encompasses other field conditions. This may be called the <em>effective<\/em> coefficient of friction.\r\n<p style=\"border: 3px solid #333399; padding: 1em; text-align: left;\"><strong>COF Defined:<\/strong> COF is defined as the ratio between the force necessary to move one surface horizontally over another and the force between the two surfaces. COF is used to predict force or tension.<\/p>\r\n\r\n<h2><strong>Factors Influencing the Value:<\/strong><\/h2>\r\nCOF is dependent on the two surfaces rubbing across each other, but multiple factors influence the value.\r\n<ul>\r\n \t<li><strong>Materials<\/strong>\u2014variations in material composition influence COF. Polymers may have added fillers or plasticizers. Metal alloys may perform differently, but more often we see difference in the smoothness of finish. Plastic coatings, metal oxides, and other surface variations will all influence COF.<\/li>\r\n \t<li><strong>Movement<\/strong>\u2014the energy to initiate motion (static COF) is higher than that required to keep the object moving (kinetic COF).<\/li>\r\n \t<li><strong>Normal Force<\/strong>\u2014higher pressure will change the surface properties as well. In cable pulling science this is seen as lower COF in bends, under high sidewall force.<\/li>\r\n \t<li><strong>Temperature<\/strong>\u2014depending on the situation and material, temperature will directly affect COF. Cable and conduit materials soften under high temperature and stiffen when cold.<\/li>\r\n \t<li><strong>Lubricant Application<\/strong>\u2014lowers the COF between two surfaces. Lubricants respond to materials differently and are also impacted by the factors above. The lubricant needs to fully coat the surface as the two materials are pressed and rubbed together. Some surfaces are more difficult than others, which is a topic for future blogposts.<\/li>\r\n<\/ul>\r\n<table style=\"width: 100%; border: 3px solid #273A80; background-color: #69c3e8; margin: 15px 0px 15px 0px;\">\r\n<tbody>\r\n<tr>\r\n<td style=\"padding: 20px; text-align: center;\"><a href=\"https:\/\/www.polywater.com\/en\/knowledge-hub\/coefficient-of-friction-in-cable-pulling-post-2\/\" target=\"_blank\" rel=\"noopener\"><strong>Related Content: <\/strong>Coefficient of Friction in Cable Pulling \u2013 Part 2<\/a><\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n<h2><strong>COF Measurement &amp; Selection<\/strong><\/h2>\r\nSo, what COF provides the best cable pulling tension estimates for field planning and optimal cable system design?

It can also be increased to account for unknown duct conditions, high conduit fill, etc. Luckily for engineers and installers, Polywater\u00ae developed and maintains a comprehensive database of effective COFs, providing users access to years of pull data.\r\n\r\nPolywater\u2019s extensive COF database, which supports our <a href=\"https:\/\/www.polywater.com\/en\/pull-planner-2\/\" target=\"_blank\" rel=\"noopener\">Pull-Planner\u2122<\/a> software was developed from actual cables and conduits. Our knowledge base is built on a variety of test methods and field results. The key to this testing is to know and measure the forces placed on the two materials in order to derive the friction coefficient. In these tests, different cable and conduit types from a variety of manufacturers and material variations are used to mimic field conditions. Our database is built with a broad selection of each material type and thousands of individual tests.\r\n<table style=\"width: 100%; border: 3px solid #273A80; background-color: #69c3e8; margin: 15px 0px 15px 0px;\">\r\n<tbody>\r\n<tr>\r\n<td style=\"padding: 20px; text-align: center;\"><a href=\"https:\/\/www.polywater.com\/en\/knowledge-hub\/coefficient-of-friction-in-cable-pulling-part-3\/\" target=\"_blank\" rel=\"noopener\"><strong>Related Content: <\/strong>Coefficient of Friction\u202fin Cable Pulling Tension from Conduit Bends<\/a><\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n<h2><strong>Summary<\/strong><\/h2>\r\nPolywater has a long history and extensive database of friction measurement.

The friction reduction lowers the force required to pull the cable into the conduit. This reduces the tension (tensile stress) on the cable during installation.\r\n<h2>Why use a pulling lubricant?<\/h2>\r\nPulling lubricants lower tension on cable as it is installed, providing numerous benefits. Lower pulling forces are less likely to physically damage the cable. Lower sidewall pressure, which is the normal pressure on a cable going around a bend can improve installation performance and life. Additionally, lower tension means less equipment wear, improved operational safety, and longer uninterrupted cable runs (fewer splices). These combined benefits result in an improved and lower-cost cable installation.\r\n<h2>Is lubricant needed for every cable pull?<\/h2>\r\nFor short, straight pulls with lightweight cable, a lubricant may not be needed. For longer pulls, pulls with a greater total bend angle, or pulls with heavy cable, the use of an effective lubricant can significantly lower tension and sidewall pressure.\r\n<table style=\"width: 100%; border: 3px solid #273A80; background-color: #69c3e8; margin: 15px 0px 15px 0px;\">\r\n<tbody>\r\n<tr>\r\n<td style=\"padding: 20px; text-align: center;\"><a href=\"https:\/\/www.polywater.com\/en\/knowledge-hub\/coefficient-of-friction-in-cable-pulling-part-1\/\" target=\"_blank\" rel=\"noopener\"><strong>Related Content: <\/strong>Coefficient of Friction in Cable Pulling \u2014 Part 1<\/a><\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n<h2>How do I know how difficult a cable pull will be?<\/h2>\r\nEquations based on the physics of the pull can provide an estimate of tension and sidewall pressure. The primary inputs into the equations are cable weight, conduit system detail (run lengths and bend location and angle), and the friction coefficient of the cable jacket against the conduit wall. The equations calculate pulling tension and sidewall pressure as the cable moves through the conduit.\r\n<h2>What is the friction coefficient?<\/h2>\r\nThe friction coefficient (or coefficient of friction) is a dimensionless number that is a measure of the frictional resistance to movement of the cable against the conduit wall. A pulling force is required to overcome this frictional force and move the cable. For example, if a 10 lb (4.5 kg) block sitting on a table took 5 lbs (2.25 kgs) of force to move it across the table, the coefficient of friction is the ratio of the pulling force to the gravitational force, or 5\/10 (2.25\/4.5), so the friction coefficient = 0.5.\u00a0 For plastic and rubber cable jackets against metal or plastic conduit, typical friction coefficients can vary from 0.1 to 1.5.\r\n<h2>How does a lower friction coefficient impact tension?<\/h2>\r\nIn horizontal straight sections of duct, the pulling tension is directly proportional to the coefficient of friction (COF). So, a reduction of 50% in the COF means a reduction of 50% in the pulling tension. However, in bend sections, the primary normal force comes from the pulling force itself, and the COF is in an exponential factor that multiplies the incoming tension. A reduction of 50% in the COF can mean a reduction of 90% in the tension in 180 degrees of bend.\r\n<table style=\"width: 100%; border: 3px solid #273A80; background-color: #69c3e8; margin: 15px 0px 15px 0px;\">\r\n<tbody>\r\n<tr>\r\n<td style=\"padding: 20px; text-align: center;\"><a href=\"https:\/\/www.polywater.com\/en\/knowledge-hub\/planning-cabling-projects-improves-success-and-safety\/\" target=\"_blank\" rel=\"noopener\"><strong>Related Content: <\/strong>Planning Cabling Projects Improves Success and Safety<\/a><\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n<h2>How do I determine which coefficient of friction to use?<\/h2>\r\nIn cable pulling, this coefficient of friction depends not only on the lubricant, but also the cable jacket type and conduit type. All three must be known to determine a meaningful COF. While there is no standard friction measurement method that applies to cable in conduit, our methods at Polywater\u00ae measure real cable friction on standard conduit types. Thousands of tests have produced a large friction database. These data are validated by back calculating effective coefficient of friction from actual cable installations. We make this data available in our lubricant technical data sheets or in our tension estimating software, <a href=\"https:\/\/www.polywater.com\/en\/pull-planner-2\/\">Pull-Planner\u2122<\/a>\r\n<h2>How much lubricant should I use for a pull?<\/h2>\r\nPolywater\u2019s Pull-Planner program determines an appropriate quantity by calculating the volume of a complete coating of the interior of the conduit and\/or the exterior of the cable jacket(s). So, the amount of lubricant recommended is proportional to both the length of the pull and the size of the cable\/duct. For cable pulling, an excess of lubricant is not a problem, but for cable blowing, you need to avoid lubricant puddling.\r\n<h2>Is COF the only important property of a pulling lubricant?<\/h2>\r\nNo. The cable pulling environment and the ability and methodology used to apply the lubricant and are both important. While liquid lubricants work neatly in underground pulls by simply pouring into a feeder tube or upturned duct, they cannot be applied to cable going into overhead conduits, thanks to gravity. Lubricants that thicken or freeze at cold temperatures cause problems in cold weather applications. Maintaining friction reduction when pulling though a flooded conduit requires unique lubricant properties.\r\n<table style=\"width: 100%; border: 3px solid #273A80; background-color: #69c3e8; margin: 15px 0px 15px 0px;\">\r\n<tbody>\r\n<tr>\r\n<td style=\"padding: 20px; text-align: center;\"><a href=\"https:\/\/www.polywater.com\/en\/knowledge-hub\/the-polywater-friction-table-personal-perspectives\/\" target=\"_blank\" rel=\"noopener\"><strong>Related Content: <\/strong>The Polywater\u00ae Friction Table: Personal Perspectives<\/a><\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n<h2>Are there other factors that raise tension during a cable pull?<\/h2>\r\nLots of them! Most factors can be managed with good pulling procedures. There are \u201cmathematical\u201d effects from the location of bends in the conduit run. Dirt or sand filled conduit can increase friction considerably, much more than can be reduced by using a lubricant. High temperatures make cable jackets softer and raise their friction. In hot climates this can sometimes be controlled by pulling at cooler times of day. In cable blowing, a compressor cooler is necessary for optimal installation lengths. Read our installation literature and technical papers for best practices on controlling pulling tension.\r\n<h2>Can mineral oil or soap be used as pulling lubricants?<\/h2>\r\nWhile these materials are friction reducers, care must be taken not to use any lubricant that can swell, weaken, or crack the cable jacket. The cable manufacturer can be a source of information on the compatibility of various lubricants with various types of cable jacket. IEEE Standard 1210 covers the testing recommended to establish the compatibility of a lubricant with cable jacket.\r\n<h2>Is it okay to use cable lubricant in prelubricated cables or conduit?<\/h2>\r\nPolywater lubricants are compatible with both prelubricated cable and prelubricated conduit. Addition of a pulling lubricant often optimizes the performance of these materials, especially in a difficult raceway configuration or particularly long run.\r\n<table style=\"width: 100%; border: 3px solid #273A80; background-color: #69c3e8; margin: 15px 0px 15px 0px;\">\r\n<tbody>\r\n<tr>\r\n<td style=\"padding: 20px; text-align: center;\"><a href=\"https:\/\/www.polywater.com\/en\/knowledge-hub\/hawaiian-electrical-company-heco-and-the-pearl-harbor-cable-pull\/\" target=\"_blank\" rel=\"noopener\"><strong>Related Content: <\/strong>Hawaiian Electrical Company (HECO) and the Pearl Harbor Cable Pull<\/a><\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n<h2>Can I run megger testing on my cable after installation?<\/h2>\r\nPulling lubricants are conductive. Residue near the splice or conductor should be completely removed before cable is energized or tested. There is no problem with lubricant residue left on the cable jacket.\r\n<h2>How does fiber optic cable pulling relate to cable blowing or jetting?<\/h2>\r\nWhile fiber optic installation methods have significantly different procedures and equipment, they rely on a force to move the cable through the conduit. In pulling, the force is on the front of the cable and comes from a pulling winch. In cable blowing, the force results from the pressure differential between the compressor end and the open end of the conduit. Blowing produces a \u201clocalized\u201d force along the entire cable jacket. Pulling and blowing need to overcome the frictional resistance to movement, and when that frictional resistance is reduced using a lubricant, pulling tension will decrease or blowing distance will increase.\r\n<h2>Can I use my fiber optic cable pulling lubricant for cable blowing?<\/h2>\r\nUsually not. Pulling lubricants use a water base to carry and spread the lubricant though the conduit. You can typically see the lubricant on the surface of the cable when it emerges from the conduit. However, this type of slippery liquid or gel does not help in cable blowing. While blowing lubricants may be carried by water, the water evaporates quickly due to high velocity air flow. Effective blowing lubricants work dry, and they are designed to reduce friction with a very thin, \u201cmolecular\u201d coating thicknesses. Excess lubricant can create too much surface tension or cause air locks, which can interfere with the installation process.\r\n<h2>Have any questions?<\/h2>\r\n<button class=\"button button--primary\" data-micromodal-trigger=\"polywater-modal--email-us-form\">Email Us <\/button>","post_title":"FAQ - Cable Pulling, Lubrication, and Tension","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"frequently-asked-questions-cable-pulling-lubrication-and-tension","to_ping":"","pinged":"","post_modified":"2025-04-16 03:54:10","post_modified_gmt":"2025-04-16 08:54:10","post_content_filtered":"","post_parent":0,"guid":"http:\/\/polywaterv2.wpengine.com\/?p=6920","menu_order":244,"post_type":"post","post_mime_type":"","comment_count":"0","filter":"raw"}},{"post_identity":{"ID":695,"post_author":"21","post_date":"2020-09-02 19:36:35","post_date_gmt":"2020-09-03 00:36:35","post_content":"<h2><strong>Measuring Friction on Polywater\u2019s Friction Table<\/strong><\/h2>\r\nPolywater<sup>\u00ae<\/sup> has measured the friction coefficient for thousands of cable, conduit, and lubricant combinations using the friction table.

All materials are cleaned, and an unlubricated control is measured. Cable and conduit are coated with a thin film of the lubricant to determine the lubricated COF. If more than one lubricant is tested, cable and conduit are cleaned or exchanged with fresh materials so that the unlubricated value matches the initial control. A pneumatic pressure cylinder pushes down on the cable. A load cell measures this normal force. A small winch pulls the conduit at a constant speed of 23 ft\/min (7 m\/min). Note that the conduit is pulled under the cable. This makes no difference in friction determination and enables data to be gathered with a relatively small piece of cable. A second load cell measures the pulling force. Both load cell measurements are simultaneously captured by a load cell scale, which takes readings every 0.1 second. The kinetic coefficient of friction is calculated from this data using the equation:\r\n\r\n<strong>\u03bc = F\/N<\/strong>\r\n\r\nWhere:\r\n\r\n<strong>\u03bc is the coefficient of friction<\/strong>\r\n<strong>F is the measured pulling force<\/strong>\r\n<strong>N is the measured normal force<\/strong>\r\n\r\nWe pull twenty (20) data points from the central part of the test and these are averaged for the final COF value. If the standard deviation is higher than 0.02 lubricated or 0.04 unlubricated, the run is discarded. Recorded results are the average of three or four separate pulls. Actual data used to develop a single COF value are shown below.\r\n\r\n<strong>Graph 1<\/strong>\r\n\r\n<img class=\"alignnone size-full wp-image-699\" src=\"https:\/\/www.polywater.com\/wp-content\/uploads\/2020\/09\/Graph-1-1.png\" alt=\"A graph showing the coefficient of friction of LLDPE cable jacket, with PVC conduit, and Polywater J lubricant.\" width=\"700\" height=\"382\" \/>\r\n\r\nThe COF variance within the short pull length and from pull to pull is captured in the graph above and tends to be relatively low.\r\n<h2><strong>Kinetic versus static friction<\/strong><\/h2>\r\nPolywater\u2019s Friction Table is set up to measure kinetic or sliding friction. The discrete data sampling that we record prohibits a determination of static friction. Regardless, kinetic friction results are the most useful and provide the best correlation with measured tension in field cable pulls. Some \u201cnon-lubricated\u201d jackets show a significant variation between the static and kinetic friction, resulting in \u201cslip\/stick\u201d (cable jumping) in pulling.<strong>\u00a0<\/strong>\r\n<table style=\"width: 100%; border: 3px solid #273A80; background-color: #69c3e8; margin: 15px 0px 15px 0px;\">\r\n<tbody>\r\n<tr>\r\n<td style=\"padding: 20px; text-align: center;\"><a href=\"https:\/\/www.polywater.com\/en\/knowledge-hub\/measuring-cable-pulling-friction-with-a-reel-test\/\" target=\"_blank\" rel=\"noopener\"><strong>Related Content: <\/strong>Measuring Cable Pulling Friction with a Reel Test<\/a><\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n<h2><strong>Statistical analysis <\/strong><\/h2>\r\nThere is another source of variation that can be more significant. This is the variation over multiple cable jackets in the same generic class. Polymeric jackets can differ in formulation and physical properties from one manufacturer to another. Metal conduits also show higher variance.\r\n\r\nPolywater\u2019s database represents well over a decade of collected data. Variations in individual results reflect the differences mentioned above. As an example, Graph 2 below shows the normal distribution for multiple tests of LLDPE-jacketed cable on three different conduit types. Steel COF data shows a higher data spread than the EMT or PVC conduits.\r\n\r\n<strong>Graph 2<\/strong>\r\n\r\n<img class=\"alignnone size-full wp-image-701\" src=\"https:\/\/www.polywater.com\/wp-content\/uploads\/2020\/09\/Graph-2.png\" alt=\"A graph showing LLDPE Cable on various conduits using Polywater J\" width=\"700\" height=\"433\" \/>\r\n\r\nCOF data offered in our literature and Pull-Planner Software represent many manufacturers and products within their grouping. It is important to realize that most friction table data are averages, and variance should be considered when the data are used. Although there is variance across conduit and cable jacket materials, cable lubrication is the biggest differentiating factor as will be shown in the next part of this paper.\r\n<h2><strong>General results from the friction table<\/strong><\/h2>\r\nAnalysis and presentation of all the conclusions gathered from the friction table are beyond the scope of this paper.

The lower COFs possible with Polywater LZ produce lower tension pulls that, in turn, allow longer conduit runs.\r\n\r\nNote that non-lubricated friction and lubricated friction vary by jacket. While the high-performance lubricant Polywater LZ is an equalizer, there is still a range in lubricated friction (0.06 to 0.11) among these jackets.\r\n\r\n<strong>Graph 3<\/strong>\r\n\r\n<img class=\"alignnone size-full wp-image-703\" src=\"https:\/\/www.polywater.com\/wp-content\/uploads\/2020\/09\/Graph-3.png\" alt=\"A bar graph showing coefficient of friction on different cable jacket types.\" width=\"700\" height=\"435\" \/>\r\n<h2><strong>Conduit effects<\/strong><\/h2>\r\nGraph 4 shows average friction coefficients for PVC jacket in several types of conduit, again both lubricated and non-lubricated.\r\n\r\nAs expected, non-lubricated friction is several times higher than lubricated (0.42 to 0.67).

The friction table represents a well-lubricated condition.\u00a0 Aspects like lubricant carrying properties cannot be measured on the machine.\r\n\r\n2. The device only works with single cable, so variables like cable configuration or multi-size cables cannot be studied. We have performed cable jamming and cable fill studies on other cable friction measurement devices.\r\n\r\n3. Certain conditions such as pulling through water-filled duct can be studied through repetitive pulls and comparative friction measurement. While these studies are cumbersome, we have conducted specialty studies, usually with other measurement devices.\r\n\r\n4. Small, flexible cables tend to \u201cbunch\u201d and do not give good results on the device.\r\n\r\n5. While the friction table can be run in various ambient conditions, its use in hot or cold rooms is not practical, so the data represent typical laboratory temperatures of 68\u00b0 F to 72\u00b0 F (20\u00b0 C to 22\u00b0 C).\r\n\r\n6. While the normal pressure on the friction table can be adjusted, a great majority of the historical data has been taken with a normal pressure in the range of 100 lbs. (445 N). While friction variation with normal pressure can be studied on the device, the use of low normal pressures raises the measurement variance significantly. So, normal pressure effects on friction have been studied using other methods.\r\n<table style=\"width: 100%; border: 3px solid #273A80; background-color: #69c3e8; margin: 15px 0px 15px 0px;\">\r\n<tbody>\r\n<tr>\r\n<td style=\"padding: 20px; text-align: center;\"><a href=\"https:\/\/www.polywater.com\/en\/knowledge-hub\/frequently-asked-questions-cable-pulling-lubrication-and-tension\/\" target=\"_blank\" rel=\"noopener\"><strong>Related Content: <\/strong>FAQ \u2013 Cable Pulling, Lubrication, and Tension<\/a><\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n<h2><strong>Summary<\/strong><\/h2>\r\nThe Polywater Friction Table offers a convenient and effective way to measure friction.
